Answered: Mesh combined causes smoothness in Quixel 3DO

Hi, i am importing a pistol model from Maya into quixel and it is two pieces that i am struggling with, the rail and the top piece of the pistol. They are seperate meshes and when they are exported together into quixel, all of the edges are smoothed (smoothened?) on the rail but when i export the rail by itself and bring it into quixel, the rail has the sharp edges that i exported it as (which is normal and what i want to look like when i import it with the top piece). Is there a way to fix this and do you know what might be causing it? Below are some links to the picture:
